    cases above recorded was it ever observed, although it was repeatedly examined for, and although the veins were in each case much distended. In many of the recorded cases no mention is made of the presence or absence of this inspiratory swelling of the cervical veins, and in some {e.g., Case 19) it is expressly stated that it was not present. We can- not, therefore, regard it as a constant sign, and one which is always present even in well-marked cases of mediastino-pericarditis. It has also been observed in an uncomplicated case of pericarditis exudativa (Boehr). It should, however, be stated that more importance in the diagnosis of mediastino-pericarditis has been attached by one observer to the presence of a pulsus paradoxus and to inspiratory distension of the right jugular vein. Schreiber^ says that the true pulsus paradoxus, as seen in mediastino-pericarditis, differs materially from the inspiratory pulse intermission, which is met with physiologically and under various other conditions. The special peculiarities and characteristics of the pulsus paradoxus, as seen in cases of mediastino-pericarditis are, according to this observer, the following :— (1) Marked diminution in the volume or complete disappearance of the pulse of all arteries, and not only of that of the radial vessels, during inspiration and especially iu the second half or at the end of that act. (2) The impossibility of replacing the paradoxical pulse by a full pulse by a prolonged and sustained inspiration. Qrapfner.
